Stenoendemic

Three stenoendemic species are considered vulnerable (VU): Paramysis kosswigi from Lake Işikli in Turkey and several springs; Paramysis lacustris turcica endemic of Lake Beyşehir in Turkey and D. hebraica, found only in three costal stream in Israel.

The subterranean habitats of the Dobra Rivers are also home to the Ogulin cave planarian (Dendrocoelum subterraneum Komárek, 1919), a Critically Endangered (CR) stenoendemic species that has only been recorded in the Ðula Sink-Medvedica cave system.

Two stenoendimics with stable populations, Trogolomysis vjetrenidensis from Vjetrencia cave in Bosnia and Herzogovinia (ca 7 km long), and D. lacustris from Lake Scutari (370 km²), on the border between Montenegro and Albania, are endangered by habitat disturbance.
